Abstract

Est divulgué un fût de matière et un séchoir d'une machine intégrée infrarouge de déshumidification, cristallisation et séchage. La forme transversale du fût de matière est un polygone ayant plus de côtés qu'un pentagone, une extrémité du fût de matière est ouverte et est une extrémité d'alimentation, chaque surface de plaque constituant le fût polygonal comprenant une partie de plaque médiane et une première partie de plaque de fermeture et une seconde partie de plaque de fermeture disposées aux deux extrémités de la partie de plaque médiane, la première partie de plaque de fermeture et la seconde partie de plaque de fermeture forment chacune un angle obtus avec la partie de plaque médiane et se ferment vers le milieu, et une paroi latérale du fût de matière est pourvue d'un orifice d'évacuation ou l'autre extrémité du fût de matière est disposée de manière ouverte comme orifice d'évacuation ; et lorsque l'autre extrémité du fût de matière est disposée de manière ouverte comme orifice d'évacuation, une plaque de guidage d'évacuation en spirale est disposée à l'intérieur du fût de matière pour faciliter l'évacuation de la matière. Le séchoir utilisant le fût de matière décrit peut présenter un meilleur effet de retournement de matière sans avoir de plaque de retournement de matière, permettant une difficulté de traitement faible, et convenant à la cristallisation et au séchage de certaines particules de plastique hautement visqueuses.
